EMBROIDERY ATTACHMENT FOR SEWING-=lVIACHlNES.

SPECIFICATION forming part of Letters Patent No. 445,953, dated February3, 1891. Application filed March 8, 1886. Serial N-194,410. (ModeL) Toall whom it may concern.-

Eleit known that I, THOMAS S. HUNTINGTON, a citizen of the UnitedStates, residing in the city, county, and State of New York, haveinvented certain new and useful Improvements in Embroidery Attachmentsfor Sewing-Machines, of which the following is a specification.

My invention relates to embroidery attachto ments of the class adaptedfor use in conjunction with the usual family sewing-machine; and itconsists in the combination of sundry parts, of which the presser-foot,vibrating arm, and lever are the-principal features directly united as aunit, which lever is operated through the medium of pivotal connectionattached to the needle-bar, all of which will be hereinafter more fullyexplained, and pointed out in the claim.

The object is to simplify the construction, arrangement, and operationof such attachment, and by such simplification in number of parts andtheir arrangement and mode of operation a cheap, effective, anddesirable cmbroiderer may be produced.

Referring to the drawings, Figure l represents a front view of myimproved attachment connected to the presser and needle bars of asewing-machine, and Fig. 2 represents an edge or side view of the same.Fig. 3 represents the thread-carrier guide and lever connected, althoughdetached from the other parts, which together form my improvements.Figs. 4- and 5 represent parts separated, which when united form thepivotal device adapted to be secured to the needle-bar, which form meansfor operating the lever of the embroiderer. Fig. 6 represents a frontview of my improved attachment, with the needle at its highest point.Fig. '7 represents a perspective view of my attachment in its properrelative position on the presser and needle bars.

In the drawings, A and B respectively represent needle and presscr barsof a sewingmachine, and O the presser-foot, in this instance serving asa frame, to which most of the operative parts are secured.

D represents an arm serving as a lever, presenting a taperingwedge-shaped front, as clearly shown in the. drawings. Said arm or leveris pivoted and secured to the shank of the presser-foot by a screw,whereby it may be tightened up so as to always have a cer tain amount offrictional contact therewith for obvious reasons, and the sides of saidarm or lever are at an angle with the center line thereof. This lever,as before explained, is pivotally attached to the shank of the presserin a position to be oscillated by a flanged device secured to the needlebar, to which flanged 6c device is pivoted another device, providedwith projections at each side thereof. The said devices are representedat a and Z) in the drawings, and will be described more fullyhereinafter. The lower end of the arm or lever D is provided withacurved thread carrying and directing arm, more clearly shown in Fig. 3of the drawings, which arm is pr0- vided with an eye for the thread ator near its free end. I sometimes form another eye or opening near thecentral part of the curve in said thread-carrier, as shown in Figs. 1,2, and Said parts a and b are in this particular instance united andsecured to the needlebar as the means for operating the arm or lever Dwhen in use. The part a (see Fig. 4C) is (so to speak) three-sided,forming a sort of bracket adapted to straddle the needlebar, and isprovided with an opening in one side thereof for the purpose ofadmitting or re- So ceiving the needle-clamping screw, by which it isheld in position, as shown in Fig. 2; The part b (more clearlyillustrated in Fig. 5) is provided with two lugs or projections arrangedthereon, as more clearly shown in said Fig. 5, and is pivoted ,to thepart a by pins or other means at points or openings indicated by thelower small circles in parts shown in Figs. at and 5, adapted to vibrateand alternately engage with projections c 0, located on either side ofthe said lever D to operate the latter and its thread-carrying arm, aswill be described more fully hereinafter. The said vibrator part b isalso provided with a curved slot or opening (clearly shown in Figs. 1and 5 5) within which a pin projecting from the part a extends andoperates, adapted to check and limit the throw of the said vibratingpiece b. which controls the vibration of the thread-carrier and lever Din their operation, as will be hereinafter more fully explained.

The several parts which together constitute my improvement may bemodified in various ways without departing from the spirit of myinvention.

It should be understood that the means for imparting motion to the leverD may be secured to the needle-bar by means of other contrivances thanthe needle-clamping screw or nut, and that the respective parts may bemodified in form, and the means for limiting the throw of the part b maybe reversed that is, the curved slot may be placed or formed within thepart a, or suitable stops might be located at points outside of theedges of the vibrating part I). These methods, as well as variousothers, would serve the requisite purpose of limiting the vibrationthereof.

The operation of my improved attachment is as follows: The presser,which serves as a frame in this instance, is attached to the presser-barwith the toe part thereof toward the needle. The part a, which supportsthe pivotally-secured part Z), is secured to the needle-bar, ashereinbefore described, and with the face of the part b with its lugsembracing the lever D, as more clearly shown in Fig.2. One end of thematerial to be carried by the controller-arm to be stitched upon thearticle to be embroidered is passed through the eye or eyes with whichthe carrying-arm is provided, and by it presented beneath the needle inoperation.

The lever D and its carrying-arm are actuated as follows: Beingsupported by the nee die-bar, as described, at the downward strokev ofthe latter one of the lugs or projections on thepart 19 engages with oneof the shoulders or projections c on the lever D. The pivotedvibrator-piece I) being secured to and carried by the needle-bar, ashereinbefore described,

lever D and tilts or throws the upper end of the same over to that side,or in the position as shown in Fig. 1, and at the upward stroke of theneedle-bar the engaging lug or projection on the vibrator-piece pushingagainst the edge of the lever D serves to push the same nearer avertical position, and at the same time tilts the vibrator-piece over tothat side (until checked by its stop-pin) in a position to bring one ofthe lugs or projections there on in a position directlyover the shoulderlocated on that side of the lever opposite the one just engaged, inorder in its downward movement to catch it and tilt the lever D to thatside, thereby actuating said lever and its thread-carrying arm.

Having thus set forth my invention, what I claim as new, and desire tosecure byLetters Patent of the United States, is

An embroidery attachment for sewing-machines, consisting of apresser-foot serving as a frame, a pivoted lever and thread-carrier arm,and an actuating device carried by the needle-bar, consisting of theplate a, adapted for detachable connection with the needlebar, and apivoted actuating-plate I), having connection therewith, the latterplate being provided with arms orprojeetions for engagement with saidpivoted lever, and an engaging pin or projection adapted to engage'witha slot in said pivoted plate I) to limit the throw thereo f,substantially as described, and for the purpose set forth.

THOS. S. HUNTINGTON.
